GEM: Ditched Comm Module

Featured Replies

So I got really fed up with the communication module in my Brultech GEM.  It's crap.  It's a cheap USR-WIFI232-B serial to net converter that half-worked at best:

  • Will likely never see a KRACK patch
  • Setup was absolutely non-intuitive
  • Security hole where the AP Wi-Fi could leak through Ethernet.
  • Had to set my switch to force 100Mbit cause it broke @ 1000Mbit
  • 3 of 4 times I'd request a webpage it failed
  • Constant issues with corrupt data being received

So, I added serial port support to NodeLink's GEM module and connect a USB-Serial adapter from my Pi to the COM port on the GEM.  I even physically removed the GEM Wi-Fi chip - good riddance.

 

Been running for about 12h, zero issues with corrupt data and the GEM web config is way smoother.  Since I'm back to a RPi (instead of Synology Docker) I'm also going to move the 1-wire back to a hardware chip and OWFS instead of the GEM bit-banging.

 

Win-Win.

io_guy,

 

Can I ask why you ditched the Synology Docker and went back to RPi?  Was it just to be able to use the USB-Serial adapter more easily?

 

I actually just did the opposite with my NodeLink setup (i.e. from RPi to Synology Docker).

Yep, cause my Pi is 5' from the GEM and Synology is 50' across a drywalled basement.  Also, the majority of people use a Pi so it helps me debug issues.

 

The Synology is a way better way to go (vs. the Pi), the location just didn't work.  I run a dozen dockers, it's fantastic (and so much faster).

Whew! :)

You had me worried that I was going in the wrong direction.
